The Atrium is a group of four different areas depending on what your mood is. There's "Dominics Downtown" with a bunch of TVs, and billiards, and video games. "The Outside Courtyard" has a dance floor and plays some pretty good Techno-type music. "The Jailhouse" is similar but with rap and reggae and more top-40 stuff. There's also a martini lounge with couches and a good, though fairly expensive bar. A good variety of activities and a nicely kept place.
